Fig. 1 is the valve control device structured flowchart according to the dryer of the embodiment of the invention.
In the dryer according to the embodiment of the invention, valve control device comprises: gas combustion chamber 20 is used to the gas that burns and supply from the valve (not shown); Inlet temperature sensor 30 is used to detect the temperature that is supplied to the inner hot blast of cylinder (not shown) through inlet; Outlet temperature sensor 40 is used to detect through the temperature of outlet from the hot blast of cylinder discharge; Valve driving portion 50,60,70 is used to operate air valve is supplied to gas combustion chamber 20 with adjusting gas flow; Control part 10; Be used for according to inlet temperature sensor 30 and outlet temperature sensor 40 detected temperature control drive divisions 50,60,70; Be supplied to the gas of gas combustion chamber 20 with adjusting, and be used to control gas combustion chamber 20 and add hot-air, with the supply hot blast through burning gases.
Especially; Valve driving portion 50,60,70 is used to regulate the gas flow that is supplied to gas combustion chamber 20; Comprise: the first one valve driving portion 50, be used to drive the first air valve (not shown), this first air valve is used to open or close the passage to gas combustion chamber 20 supply gas; The second one valve driving portion 60 is used to drive the second air valve (not shown), and this second air valve is used to open or close the passage to gas combustion chamber 20 supply gas; And proportional control valve drive division 70, being used to drive the proportional control valve (not shown), this proportional control valve is used for controlling in proportion the gas flow that is supplied to gas combustion chamber 20.
Can reference be, said dryer has the air valve of regulating the gas flow that is supplied to gas combustion chamber 20, and; For the purpose of the safety; Said dryer possesses two air valves usually, and therefore, the air valve of present embodiment in specification of the present invention, also is divided into first air valve and second air valve describes.
Therefore, in the present embodiment, the structure that is divided into first air valve, second air valve and proportional control valve with air valve is that example describes.
But, it should be noted that technical scope of the present invention does not receive the above-mentioned restriction that possesses the situation of first air valve, second air valve, also can comprise the situation that possesses at least more than one air valve.
Fig. 2 is the Air Valve Control method flow diagram according to the dryer of the embodiment of the invention.
In Air Valve Control method according to the dryer of present embodiment; S10: when the user was dried run signal through the input of keyboard (not shown), the control part 10 control first one valve driving portions 50 and the second one valve driving portion 60 were to open first air valve and second air valve.In addition, control part 10 control ratio control valve drive divisions 70 are opened proportional control valve, and in the case, and the openness of proportional control valve is transferred to maximum.In addition, through control gas combustion chamber 20 burning gases.
S20: control part 10 judges whether inlet temperature sensor 30 detected inlet temperatures are greater than or equal to inlet control temperature.
If inlet temperature is lower than inlet control temperature, then carry out S50: judge whether outlet temperature sensor 40 detected outlet temperatures are greater than or equal to valve closing control temperature.
If the temperature of outlet is lower than valve closing control temperature, then keeping under the situation of current state, return and carry out S20: judge once more whether inlet temperature is greater than or equal to inlet control temperature.
In addition; If outlet temperature sensor 40 detected outlet temperatures are greater than or equal to valve closing control temperature; Then carry out S52: close first air valve, second air valve and proportional control valve through controlling the first one valve driving portion 50, the second one valve driving portion 60 and proportional control valve drive division 70, thereby blocking-up is supplied to the gas of gas combustion chamber 20.Why like this block gas supply, even be because inlet temperature is low, but the washings of drum also may sustain damage because of outlet temperature is high.
Be greater than or equal to inlet control temperature if confirm inlet temperature among the S20, then carry out S30: judge whether outlet temperature sensor 40 detected outlet temperatures are greater than or equal to valve closing control temperature.
According to embodiments of the invention, when inlet temperature is greater than or equal to inlet control temperature, judge whether outlet temperature is higher than valve closing control temperature; When inlet temperature is lower than inlet control temperature; Judge still whether outlet temperature is higher than valve closing control temperature, and this is because the temperature of tube inlet is not how; The temperature of outlet all possibly be greater than or equal to valve closing control temperature, perhaps is lower than valve closing control temperature.In other words, if the drum washings comprises a lot of moisture, even then inlet temperature is high, the temperature of outlet also might be low.That is, if the drum washings comprises small amount of moisture, even then inlet temperature is low, the temperature of outlet also might be high.
In addition; If outlet temperature is greater than or equal to valve closing control temperature; Then carry out S60: because of being in the too high state of entrance and exit temperature, close first air valve, second air valve and proportional control valve through controlling the first one valve driving portion 50, the second one valve driving portion 60 and proportional control valve drive division 70.Thereby blocking-up is to the gas of gas combustion chamber 20 supplies.
Especially, because of valve closing control temperature is provided with decision according to the user, as valve closing being controlled temperature confirm as various situation according to the set drying time of user, washings kind and quantity or conditions of similarity.The situation of the open temperature of valve that said user states after being provided with and also can be applicable to.
In addition; If S30 confirms outlet temperature sensor 40 detected outlet temperatures and is lower than valve closing control temperature; Then carry out S40: step-length is preset in the openness reduction of proportional control valve through control ratio control valve drive division 70; As reduce a step-length, and be supplied to the gas flow of gas combustion chamber 20 with minimizing, then carry out S42: whether monitoring finishes time delay.
At this, why reduce the openness of proportional control valve, even be because outlet temperature is lower than valve closing control temperature, but may be because of excessively hot blast is impaired when inlet temperature is greater than or equal to inlet control temperature near the washings of porch.
At this moment,, then return and carry out S20: judge whether inlet temperature is greater than or equal to inlet control temperature, and carry out aforesaid operations thereafter if finish time delay.That is to say; Whenever inlet temperature is greater than or equal to inlet control temperature, and outlet temperature is when being lower than valve closing control temperature, reduces a step-length with the openness of proportional control valve is each; Be supplied to the gas flow of gas combustion chamber with minimizing, thereby prevent that inlet temperature from excessively raising.
In addition; Through confirming that outlet temperature is greater than or equal to valve closing control temperature and controls after the first one valve driving portion 50, the second one valve driving portion 60 and proportional control valve drive division 70 close first air valve, second air valve and proportional control valve, carry out S70: judge whether outlet temperature sensor 40 detected outlet temperatures are less than or equal to the open temperature of controlling of valve at S60, S52.At this moment, if outlet temperature surpasses the open control of valve temperature, repeat then to judge whether outlet temperature sensor 40 detected outlet temperatures are less than or equal to the operation of the open control of valve temperature.
In this process, since not to gas combustion chamber 20 supply gas, cylinder also just can not get the supply of hot blast.Therefore, outlet temperature will reduce gradually, and finally reach or near the open control of valve temperature.
Therefore, reach or, then carry out S80 when outlet temperature: through controlling the first one valve driving portion 50, the second one valve driving portion 60 and proportional control valve drive division 70 open first air valve, second air valve and proportional control valves near the open control of valve temperature.Like this, proportional control valve drive division 70 transfers to final openness with the openness of proportional control valve, and this final openness is the openness of proportional control valve when closing.
Afterwards, return executable operations: judge whether inlet temperature is greater than or equal to inlet control temperature, the aforesaid operations behind the retry Xingqi of laying equal stress on.In said process; For example; If surpass the drying time of carrying out drying operation or satisfy the condition that stops drying operation; Dryness fraction like washings reaches conditions of similarities such as requirement, then is supplied to the gas of gas combustion chamber 20 through controlling the first one valve driving portion 50, the second one valve driving portion 60 and 70 blocking-up of proportional control valve drive division, and the rotation that stops cylinder is to stop drying operation.Because this is the content that those skilled in the art realize easily, therefore, repeats no more at this.
As stated; The Air Valve Control method of the dryer of the embodiment of the invention; Not only based on the temperature of outlet, but also based on coming by-pass valve control to the inlet temperature of drum supply hot blast, therefore; Even, also can bake out temperature be maintained preset temperature for reaching identical caloric value burn gas such as compressed petroleum gas (LPG), the liquefied natural gas (LNG) etc. of different amounts.Although describe the present invention in conjunction with accompanying drawing and embodiment; The foregoing description is only unrestricted in order to explanation the present invention; Those of ordinary skill in the art is to be understood that; Can make amendment, be out of shape the present invention or be equal to replacement, and not break away from the spirit and scope of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
